Check the picture below.
surely, you'd know how much that is.
The answer would be d , because you have to add how many of each fish to equal up to the sum of 420 . which is x y . so the first equation is x + y = 420 . then it says he bought 6 times as many parrotfish as he did angelfish so you would have to multiply x which represents angelfish by 6 . to get the second equation of y = 6x .
Answer:
The correct option is B)
.
Step-by-step explanation:
Consider the provided information.
Angle A C B is 90 degrees and angle A B C is 35 degrees.
The required figure is shown below:
We need to find the value of c.
Use the trigonometric function: 


Hence, the correct option is B)
.
Answer:
From the frequency table, let's calculate the row total.
Row total for phone call = 19 + 9 = 28
Row total for no phone call = 8 +6 = 14
To calculate their respective row relative frequencies, let's use:
Row relative freq =
Now, the two-way frequency table will be computed as:
For phone call:
Desirable behavior =
≈0.69
Undesirable behaviour =
≈0.32
No phone call:
Desirable behaviour =
≈ 0.57
Undesirable behaviour =
≈ 0.43
The complete two-way table is attached.
Celia bought a bag of 12 goldfish for $3, Cost of 1 goldfish is $0.25 .
<u>Step-by-step explanation:</u>
The goldfish is a freshwater fish in the family Cyprinidae of order Cypriniformes. It is one of the most commonly kept aquarium fish. A relatively small member of the carp family, the goldfish is native to East Asia.
Here we have , Celia bought a bag of 12 goldfish for $3 . We need to find the cost of 1 goldfish . Let's find out:
Celia have a bag of 12 goldfish which cost her $3 . So , cost of 1 goldfish is equivalent to
⇒ 
⇒ 
⇒ 
⇒ 
Therefore, Celia bought a bag of 12 goldfish for $3 , Cost of 1 goldfish is $0.25 .
